and expeditious manner without fear of casual displacement or loss ofthe device, with the result the device will adapt ordinary shoes for usein playing golf and other purposes where spiked shoes are desired ornecessary.

A further object of the invention is to provide a spike bearing devicethat is formed from wire and is held associated with shoes by theinherent resiliency of the wire.

Another object of the invention is to'provide a spike device that isadapted to bedetachably associated with shoes and renders ordinary shoescapable of performing all the functions of spiked shoes that have spikespermanently fixed thereto. 1

A still further object of the invention is to provide a spike devicethat is simple in construction, inexpensive to manufacture, easy toinstall and extremely eflicient in operation and service.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawing andspecifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawing wherein like characters denote like orcorresponding parts throughout the several views, and in which:

Figure 1 is a top plan view of one form of my invention applied to ashoe sole.

Figure 2 is a modified form.

Referring to the drawing in detail and particularly to Figure 1, theletter A indicates a shoe sole which receives the device in the manneras illustrated in Figure 1, and the device in this form is provided witha pair of cooperating single strands of resilient wire which are ofidentical shape but for distinction are indicated by the referencenumerals 1 and 2.

Each of the strands of wire 1 and 2 have their ends bent at right anglesto form what may be termed jaws 3 which are in the form move of studs,and from the jaws the strands of wire are curved upon themselves, thenceare bent to form L-shaped members 4 which provide' spikes, the long armsof the L-shape,

members 4 being disposed in contactin engagement with the bottom ofthesole 0 the shoe, while the short arms act in the capacity as groundpenetrating elements.

The strands of wire are twisted in coil.v

formation about each other midway between their ends, and midway betweenthe ends of the coiled portion which is indicated by the referencenumeral 5, the strands extend laterally in opposed relation to providein-. termediate L-shape members 6.

In forming the substantially L-shape members 4 and 6, it will be notedthat the portions of the wire providing these members are arranged incontacting engagement, and due to,

the fact that the long arms of the L-shape 7- members are arranged inengagement with the bottom of the sole, it will be apparent that thepressure upon the long arms'will urge the ground penetrating portionsdownwardo, ly, and in a manner whereby displacement of the members orbending the same outof shape is reduced, to a minimum.

In the formof the invention as shown in Figure 2, I also employ twostrands of wire shaped substantially similar'to the strands 1 and 2, andfor distinction the strands of the wire as shown in Figure 2 areindicated by the reference numerals 7 and 8. Each of' the strands 7 and8 are curved in substantially semi-circular formation and includes jaws9 for engagement with the shoe soles, and subin one direction, thestrands 7 and 8 will b x d away from each other and by rotating 1 theshaft in an opposite direction, the strands 7 and 8 will be moved towardeach other.

From the above description and disclosure of the drawing, it will beobvious that I have provided a spike device that can be utilized onordinary shoes so as to cause the latter to perform the function ofspike shoes or shoes that have spikes permanently fixed thereto and dueto the inherent resiliency of the 10 strands of Wire from which Iprovide the spike devices, the devices are capable of fittingpractically all sizes of shoes and are held upon the sole of the latterby the pressure of the jaws against the outer edges of the soles in amanner to prevent casual displacement or loss of the devices. The formas shown in Figure 2, has of course ,a greater latitude of adjustmentand will probably fit every size of shoe. It is thought from theforegoing description that the advantages and novel features of myinvention will be readily apparent. I desire it to be understood that Imay make changes in the construction and in the combination andarrangement of the several. parts, provided that such changes fallwithin the scope of the appended claims.

What I claim is: 1.- A spike attachment for shoes comprising strands ofresilient wire bent in substantially semi-circular formation, and coiledabout each other midway their ends, jaws formed with the ends of saidstrands and being engageable with the sole of ashoe for detachablysecuring the attachment to said sole, spike means formed with saidstrands and being substantially L-shaped, and said spike means havingtheir long arms engageable with the sole and their short arms eX-tending at right angles with respect to the long arms to provide groundpenetrating means.

2. A spike attachment for shoes comprising a pair of strands ofresilient wire bent in curved formation and being coiled about eachother midway their ends, jaws formed with the ends ofsaid strands andengageable with the sole of ashoe for detachably secur-' ing theattachment to said sole, said strands being bent at intervalsintermediate their ends to provide substantially L-shaped spike. means,and L-shape spike means formed with said strands and extending inopposed relation from the coil portion, In testimony whereof I affix mysignature.

JOHN LAW KERR.
